ANGULAR DISTRIBUTION AND RANGES OF N$sup 13$ PARTICLES RESULTING FROM 27.5- Mev N$sup 14$ IONS ON Mg$sup 2$$sup 4$
The angular distribution and ranges are reported for N/sup 13/ nuclei resulting from the transfer reaction Mg/sup 24/(N/sup 14/,N/sup 13/)Mg/su p 25/ (Q = -3.22 Mev) at an incident N/sup 14/ energy of 27.5 Mev. The data are compared to those reported previously for the reaction M/sup 25/(N/sup 14/, N/sup 13/)Mg/sup 26/(Q = 0.57 Mev) to study the effe ct of Q. It is found that while the angular distributions are similar in shape, Mg/sup 26/ states up to 7-Mev excitation contribute significantly to the reaction Mg/sup 25/(N/sup 14/,N/sup 13/ )Mg/sup 26/ in contrast to the presented Mg/sup 24/ data which show no Mg/sup 25/ states above --5 Mev contributing to the transfer process. The N/sup 13/ ranges when expressed as a function of Q indicate the bulk of N/sup 13/ particles lying between similar Q values for both reactions. Excited-state transfers predominate in the two magnesium reactions in contrast to results reported at the same N/sup 14/ incident energy for B/sup 10/ and N/sup 14/ targets in which ground-state transfers accounted for approximately half of the total cross sections. The angular distributions are replotted as d sigma /dR/sub min/ vs R/sub min/ and r/ sub o/'s calculated for the peak values of R/sub min/; the r/sub o/'s are 1.6 f and 155 f for Mg /sup 24 and Mg/sub 25/ targets, respectively. The magnesium data are compared to the tunneling theory for transfer reactions and fair agreement is found. (auth)
